DABBING APPARATUS FOR WOOL-COMBING MACHINES.

SPECIFICATION forming part of Letters Patent No. 479,695, dated July 26, 1892.

Application tiled February 5, 1892. Serial No. 420,403. (No model.)

To all whom t may concern: to the cam-carrier G, which is guided in ways Be it known that I, JAMES L. BALLANTYNE, in the box-bracket C, and is preferably proa citizen of the United States, and a resident vided with 'hardened-steel faces g g, against of Newton, in the county of Middlesex and which the cam-ring f acts during its rotation. 55 State of Massachusetts, have invented new G is an upwardly-projecting stem on the and useful Improvements in Dabbing Appacam-carrier G, which stem passes through a ratus for Vool-Oombing Machines, of which stuffing-box in the upper end of the boX- the following, taken in connection withthe bracket O and is connected by means of an accompanying drawings, is a specication. arm G to the upper end of the sliding plate 6o Io This invention relates to improvements on E, as shown and described in my aforesaid the patent granted to me .Iune 4, 1889, No. Letters Patent. 404,376, for dabbing apparatus for wool-comb In devices of this kind, where a rotary cam ing machines, and it is carried out as follows, or eccentric is employed for the purpose of reference being had to lthe accompanying imparting a reciprocating motion to the dab- 65 drawings, whereinhing-'brush and its cam-carrier, it has been Figure l represents a front elevation of my found that the wear on the said cam occurs present invention and Fig. 2 represents a vermainly at one place on its periphery-that is, tical section of the same, parts of which are the place located farthest from the axis of the shown in elevation.

The interior common in wool-combing machines. of the box-bracket O is filled with a liquid C is the box-bracket, secured to the pillar lubricant, as described in my aforesaid patent, 85 A and provided with a cover D, in which is for the purpose of properly lubricating the guided the sliding plate E, to the lower end of working parts therein, so as to render the acwhich is secured the dabbing-brush c, as usual. tion Vof said parts as nearly noiseless as pos- In bearings in the box-bracket C and cover sible.

The said cam a manner as to cause the latter to enter and F is surrounded by a loosely-fitting ring f, leave the bristles of the rotating circle-comb preferably made of phosphor-bronze or other B and to move less quickly when the dab- 95 suitable metal, and to prevent said ring from hing-brush is raised above the said circlegetting detached from the cam while in use I comb, for the purpose of causing the Wool to secure to the smaller end of said cam a bridge be uniformly pressed or dabbed between the or bal-f', the ends of which projectto the outer bristles of the rotary circle-comb without edge of the loose ringf, or nearly so, as fully causing the bristles of said dabbing-brush :co 5o shown in Figs. 3 and 4. The cam and its ring and rotary comb to be dragged or bent out of when rotated impart an up-and-down motion perpendicular by the horizontal travel of the circle-comb, and for this purpose I use the following mechanism: To the driving-shaft a is secured a gear I-I, the teeth of which mesh in the teeth of a gear or pinion I, looselyjournaled on a pin or stud i, suitablysecured to a stationary bracket A,as shown in Figs. I and 2. To the gear I is secured an eccentric, elliptic, or cam-'shaped gear K, the teeth of which mesh in the teeth of a corresponding eccentric, elliptic, or cam-shaped gear L, secured to the outer end of the cam-shaft F, as fully shown in said Figs. I and 2.

From the above it will be seen that a positive variable reciprocating motion is imparted to the dabbing-brush from the driving-shaft a, for the purpose set forth.

I Wish to state that I do not desire to confinemyself to the precise number and arrangement of gear-Wheels as shown in the drawings, as such may be varied according to the construction of woolcombing machine on which the dabbing deviceis to be used Without departing from the essence of my invention, it being only essential to impart from the driving-shaft a positive variable motion to theA dabbing-brush for the purpose stated.

Having thus fully described the nature, construction, and operation of my invention, I Wish to secure by Letters Patent and claim- I. In a dabbing apparatus, the combination of a variably-reciprocating dabbing-brush, a driving-shaft, a rotary shaft having a cam or eccentric thereupon, a ring loosely j ournaled on the cam or eccentric, a reciprocating camcarrier connected With the dabbing-brush, and gearing between the driving-shaft and the cam-shaft for imparting a variable reciprocating motion to the dabbing-brush, substantially as described.

2. In a dabbing apparatus, a variably-reciprocating dabbing-brush, in combination With a rotary shaft having a cam, a drivingshaft, and gear connections between the driving-shaft and cam-shaft for impartinga positive variable reciprocating motion to the dabbing-brush, substantially as described.

3. In a dabbing apparatus, the combination, With a rotary driving-shaft, of a variably-reciprocating dabbing-brush and gearing connecting the driving-shaft and brush for imparting a variable reciprocating motion to the latter, substantially as described.

4. In a dabbing apparatus, the combination, With a rotary comb-circle and a rotary driving-shaft, of a variably-reciprocating dabbingbrush and gearing connecting the shaft and brush for imparting a variable reciprocating motion to thelatter,substantially as described.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing Witnesses, on this 3d day of February, A. D. 1892.

JAMES L. BALLANTY'NE.
